  • System and method for providing high power factor wired lamp control
    Patent number: 11395396
    Abstract: A system and method for providing high power factor wired lamp control that include receiving a lighting control input though a switch that is associated with at least one of: an operation and a function of at least one lamp. The system and method also include determining if an environment of the at least one lamp includes a connection between a neutral wire and the switch. The system and method additionally include communicating at least one electronic data command associated with the lighting control input to the at least one lamp through an AC power cycle. The system and method further include controlling the at least one lamp to operate based on the lighting control input based on the receipt of the at least one electronic data command communicated through the AC power cycle.
    Type: Grant

  • System and method for providing high power factor wired lamp control
    Patent number: 11057981
    Abstract: A system and method for providing high power factor wired lamp control that include receiving a lighting control input though a switch that is associated with at least one of: an operation and a function of at least one lamp. The system and method also include processing a digital data packet that includes at least one electronic data command associated with the lighting control input. The system and method additionally include implementing at least one powerline interruption associated with an AC power cycle to communicate the digital data packet to the at least one lamp. The system and method further include controlling the at least one lamp to operate based on the lighting control input based on the receipt of the digital data packet communicated through the AC power cycle.
